Open positions

We currently have open positions at all levels (Bachelor, Master, PhD, or SHK).
If you are intestested in the research of the AK Steinrück, please contact Jun.-Prof. Dr. Hans-Georg Steinrück at hans.georg.steinrueck@uni-paderborn.de.

Some specific thesis topics are:

  • The role of the electric double layer in electrolyte stability (Bachelor, Master, PhD) link to flyer
    This project aims at probing experimentally the arrangement of solvent molecules and salt ions near electrodes within the electric double layer and correlating this insight with electrolyte stability. For this purpose, precision electrochemical measurements are combined with a variety of x-ray techniques such as surface scattering and small angle scattering. Baseline aqueous and non-aqueous electrolytes are of interest. The project may involve travel to international user facilities such as DESY (Hamburg), SSRL (Stanford), APS (Chicago), and ESRF (Grenoble).
     
  • Passivation of silicon anodes for lithium-ion batteries: The effect of electrolyte additives (Bachelor, Master, PhD, SHK) link to flyer
    This project aims at investigating the passivating nature of electrolyte additives with specific focus on silicon anodes for lithium ion batteries. Additives are added in small amounts to electrolytes but have a tremendous impact on improvements of battery performance. Precision electrochemical measurements on model thin films are combined with chemical characterization and operando X-ray reflectivity to relate compositional and structural properties of passivation layers with electrolytes’ functionality. The project may involve travel to international user facilities such as DESY (Hamburg), SSRL (Stanford), APS (Chicago), and ESRF (Grenoble).
     
  • Understanding transport in electrolytes via X-ray photon correlation spectroscopy (Master, PhD) link to flyer
    This project aims at gaining predictive knowledge of how ions move from one electrode to the other through the electrolyte in electrochemical systems. Here, the driving forces are migration, diffusion, and convection. Via advanced X-ray photon correlation spectroscopy, our goal is to measure electrolytes’ dynamics operando at various length scales which are correlated to microscopic and macroscopic transport phenomena. The project may involve travel to international user facilities such as DESY (Hamburg), SSRL (Stanford), APS (Chicago), and ESRF (Grenoble).
     
  • Selectivity in desalination batteries (Bachelor, Master, PhD, SHK) link to flyer
    This project aims at unravelling foundational knowledge regarding the selectivity of desalination battery electrodes towards specific ions. This is achieved via relation electrochemical insights with operando measurements of the structural and composition evolution via synchrotron scattering and spectroscopy methods. Furthermore, the project involves effort towards the rational selection of materials for high selectivity in terms of their thermodynamic and kinetic properties. The project may involve travel to international user facilities such as DESY (Hamburg), SSRL (Stanford), APS (Chicago), and ESRF (Grenoble).
